PETYA – Darwinism applied to cyberspace

PETYA ransomware struck on 27 June. The cure was released in April. Why did anyone get infected?

ISACs to the rescue

Information Sharing and Analysis Centers (ISACs) in the U.S. were able to get ahead of the infection thanks to early warning and quick action. The Downstream Natural Gas and Electric ISACS combined forces to collect, analyze, and alert their sector members, providing early indicators and even links to algorithms successfully used to earlier decrypt the PETYA ransomware. Having just recently experienced the WannaCry worm, their members were patched and defended. There were no reports of infection in electric or downstream natural gas sectors.
